Thanks guys, I thought it would be fine too but I have heard sme christians say we are commanded to be fruitful and multiply so we shouldn't stop our selves from multiplying.
I figured that would come up, and to be honest that's the goofiest interpretation of those verses that I could possibly imagine. That command was specifically to Adam and Eve and to Noah and his family, who were at the time of that command the only human beings on the entire planet, so obviously it was rather important for them to have kids.
Even if we do allow the assertion that that command was directed at all humankind rather than to those specific people and their immediate descendants (which it was not - how would we reconcile it with the statement that it is good for men not to marry if it was?), then if we are to take that verse to mean that we must do everything we possibly can to make babies, then we would have to conclude that every single second during which a woman is fertile but not pregnant, she is sinning against God. I do not think that any Christian on Earth would agree with this, yet this is the necessary ultimate end of the assertion that condoms are sinful because they keep us from procreating.
